The J1MAP-12XL is a 12 VDC relay designed for reliable switching and control applications in communications and instrumentation systems. It features a coil resistance of 500 ohms ±10% at 25°C with a nominal operating voltage of 12.0 VDC, a must-operate threshold of 7.0 VDC, and a must-release voltage of 4.0 VDC maximum with 0.63 VDC minimum. The relay has a 5-pin configuration with contact ratings from low level to 1A at 28 VDC resistive, rated for 100,000 operations, and exhibits fast switching characteristics with operate time of 2.0 ms maximum, release time of 2.0 ms maximum, and contact bounce of 1.5 ms maximum. It is qualified to withstand harsh environmental conditions including vibration from 10 CPS to 3000 CPS at 30 g's, shock of 75 g's for 6 ms duration, and operates reliably across a temperature range of -65°C to +125°C, making it suitable for aerospace, military, and industrial control applications.
